Last year I had 6 blue bonnents in my side yard garden. This year - there are to many to count! I hope that it keeps increasing every year. In the middle of the blue bonnets I planted 2 different kinds of tulips - that should both naturalize and more will come back every year. Wow - watching this area this past few weeks has been amazing. Here are some photos (that don't do it justice) of the process.
